First, are you working with phpBB 3.0 or 3.1? If you're using 3.0, you're asking at the wrong place -- this board is for development of upcoming versions of phpBB. You should ask at phpBB.com.

Second, if you are using 3.1, what is "logbook"? Is that a program, your term for the ACP log pages or something else?

Finally, I've always found that links work fine without the session IDs. If you click them and a session ID is necessary, it will be appended. But knowing exactly what you're trying to do (if you're using phpBB 3.1) would be a big help.
